DCConnect  proposes a new Distributed Ledger Technology (DLT) architecture based on Proof of Availability (PoAV) – a proof for verifying the service parameters and Service Levels Agreement (SLA) committed by service providers. Proof of Availability is a sequence of computation that can provide a way to cryptographically verify parameters.

Some key parameters of SLA are tracked on Proof of Availability. Service validators who are verifying the service level parameters submit the proof. At initial stage, key service level parameters include but not limited to:

1.  Service Coverage;
2. Committed Service Uptime;
3. Committed Service Delivery Lead time;
4. Committed Service Restoration Lead time;
5. Round Trip Delay (RTD) of network connectivity, also known as “latency”;
6. Jitter of network connectivity;
7. Packet Loss of network connectivity;
8. Others which applicable to other services.

Any violation on the committed SLA will trigger the execution of Smart Contract programmed on the DLT. Once the Smart Contract is executed, a negative impact on the credit rating of that service provider which violates the SLA will be issued, therefore, the credit rating of that service provider will decrease. The Credit Rating is an open information transparent to all buyers and sellers. The result is any service providers would make their efforts to ensure the committed SLA is fulfilled to any buyers, thus the service quality of the entire telecommunication market will be uplifted.

12 April 2021 – MEF members HGC Global Communications
(HGC), DCConnect Global, and QLC Chain under the auspices of MEF have successfully collaborated in their MEF Proof-of-Concept (PoC) that leverages MEF Lifecycle Service Orchestration (LSO) APIs with Distributed Ledger Technology (DLT) to create Smart Bilaterals for end-to-end ordering, billing and settlement of data services.
